Greilich's cut losing the finally bf!

Long story short, Ive had a long journey, starting out age 21; 317lbs and frustrated I began workout out and dieting. Fast forward 3 years I'm roughly 185 lbs, losing 135-140 lbs. Ive been 185 for the past 2 years, struggling to cut the last bit down I dieted harder and trained hard than before last march and dropped to 176lbs, 12% bf, I felt weak and small and laxed on my workout routine after injuring my shoulder. Well now I'm back at 185 17% bf or greater (tough due to extra skin from the rapid weightloss). I'm considering this week 1 back on a strict routine after successful sticking to diet and training the previous week.
